Resumo: This study compares sampling methods based on plots of fixed area and based on a fixed number of trees. The study was conducted in a Eucalyptus forest surveyed using three plot types: rectangular with fixed area, circular with fixed area and fixed number of trees. The estimation accuracies were evaluated for the average diameter per plot and for the number of stems, the basal area and the volume per plot. The null hypothesis of equality between the sampling methods was assessed by t-test. No significant differences were found between the three sampling methods.

O estudo foi realizado em um povoamento de Eucalipto, inventariado empregando os três tipos de parcela, assumindo um erro de amostragem máximo de 10%, a 95% de probabilidade. Foram avaliadas a precisão das estimativas de diâmetro médio, número de fustes, área basal e volume por hectare. A hipótese de igualdade entre as estimativas obtidas foi avaliada empregando o teste t, em nível de 5% de significância. Não foram verificadas diferenças significativas entre as estimativas obtidas pelos diferentes métodos de amostragem.Revista Árvore2018-01-08T10:56:27Z2018-01-08T10:56:27Z2016-03-03info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf1806-9088http://dx.doi.org/10.1590/0100-67622016000300016http://www.locus.ufv.br/handle/123456789/16123engv. 40, n. 3, p. 529-533, Mai./Jun. 2016Almeida, Danilo Roberti Alves deLeite, Helio GarciaGorgens, Eric Bastosinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFV2024-07-12T06:33:03Zoai:locus.ufv.br:123456789/16123Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T06:33:03LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false
